Grid Guardians

Robots march in from the right. Two columns stand between them and everything
you've built. Hold the line.

Grid Guardians is a turn-based tower defence you play one tap at a time.
Nothing moves until you do — so there's no panic, no twitch, just the next
decision and whether it was the right one.

HOW IT PLAYS

Tap a turret, then tap where you want it. The board lights up to show every
legal move before you commit: amber for an empty tile, green for a merge, blue
for a swap. Dragging works too, if that's how your hands think.

Two matching turrets merge into one that's twice as strong. That's the whole
ladder — 1, 2, 4, 8, all the way to 256 — and every run is the story of how far
up it you got before the robots stopped caring.

Power cores drift in with the enemy line. Break them and they fly to your hand.
Nothing to move this turn? END TURN lets the robots come to you.

THE RUN

There are no levels and no ending. There's just the turn you're on, and the
turn count is your score.

The early robots are small and slow. Then they aren't. Past turn 100 the siege
changes: lane gates plant themselves mid-board and swallow the fire aimed past
them — and every robot queued behind one gets tougher while it stands. Fog
rolls over the dock so you meet new arrivals a turn late. Elite units arrive
worth five ordinary ones.

Three boosters buy you a turn when a row is about to break: Firestorm clears
it, Freeze stops it, Double Attack doubles a turret for one volley.

BUILT FOR PHONES

Short turns and no clock ticking at you. Pick it up for one move while the
kettle boils, or lose an hour to a run that keeps not ending.

Five hearts, refilling over time. Optional ads for a revive or an extra
booster, and packs if you'd rather skip them. Everything in the game can be
reached without paying.
